Hybrid Improvement of Jersey Cattle Crossbreeding with Tibet Local Yellow Cattle

The investigation for hybrid improvement of Jersey cattle crossbreeding with Tibet local yellow cattle was conduct in this study. The results showed that:(1)The chest, cross department of higher body measurements for the F1 generation have significantly improved, birth weight and body weight were significantly improved.(2)By the investigation for 15 primiparous cows, milk production of a crossbred cow was 1594.1kg higher than a local cattle.
